Quick Overview - In its typical configuration, using FreeBSD as a SLIP server works as - follows: a SLIP user dials up your FreeBSD SLIP Server system and logs - in with a special SLIP login ID that uses /usr/sbin/sliplogin - as the special user's shell.

Quick Overview - In its typical configuration, using FreeBSD as a SLIP server works as - follows: a SLIP user dials up your FreeBSD SLIP Server system and logs - in with a special SLIP login ID that uses /usr/sbin/sliplogin - as the special user's shell.

Quick Overview - In its typical configuration, using FreeBSD as a SLIP server works as - follows: a SLIP user dials up your FreeBSD SLIP Server system and logs - in with a special SLIP login ID that uses /usr/sbin/sliplogin - as the special user's shell.
